Hamiltonian paths in Cayley graphs

open access: yesDiscrete Mathematics, 2009
AbstractThe classical question raised by Lovász asks whether every Cayley graph is Hamiltonian. We present a short survey of various results in that direction and make some additional observations. In particular, we prove that every finite group G has a generating set of size at most log2|G|, such that the corresponding Cayley graph contains a ...

On the Coherent State Path Integral for Linear Systems [PDF]

open access: yes, 2005
We present a computation of the coherent state path integral for a generic linear system using ``functional methods'' (as opposed to discrete time approaches).

Decomposing the Complete Graph Into Hamiltonian Paths (Cycles) and 3-Stars

open access: yesDiscussiones Mathematicae Graph Theory, 2020
Let H be a graph. A decomposition of H is a set of edge-disjoint subgraphs of H whose union is H. A Hamiltonian path (respectively, cycle) of H is a path (respectively, cycle) that contains every vertex of H exactly once.

Problems on Shortest k-Node Cycles and Paths

open access: yesКібернетика та комп'ютерні технології, 2021
The paper is devoted to the construction of mathematical models for problems on the shortest cycles and paths, that pass through a given number of nodes of a directed graph.

De-Signing Hamiltonians for Quantum Adiabatic Optimization [PDF]

open access: yesQuantum, 2020
Quantum fluctuations driven by non-stoquastic Hamiltonians have been conjectured to be an important and perhaps essential missing ingredient for achieving a quantum advantage with adiabatic optimization.

An evaluation of the number of Hamiltonian paths [PDF]

open access: yesJournal de Physique Lettres, 1985
The number of Hamiltonian walks on a regular lattice of N points, with coordination number q is of the form ωNH for N → ∞. We obtain an estimate ωH ∼ q/e in surprising agreement with available data in two dimensions.

Irreducible Hamiltonian BRST approach to topologically coupled abelian forms [PDF]

open access: yes, 1999
An irreducible Hamiltonian BRST approach to topologically coupled p- and (p+1)-forms is developed. The irreducible setting is enforced by means of constructing an irreducible Hamiltonian first-class model that is equivalent from the BRST point of view to

Length minimizing Hamiltonian paths for symplectically aspherical manifolds [PDF]

open access: yes, 2002
In this paper we consider the length minimizing properties of Hamiltonian paths generated by quasi-autonomous Hamiltonians on symplectically aspherical manifolds. Motivated by the work of L. Polterovich and M.

Energy Conditions for Hamiltonian and Traceable Graphs

open access: yesUniversal Journal of Mathematics and Applications, 2019
A graph is called Hamiltonian (resp. traceable) if the graph has a Hamiltonian cycle (resp. path), a cycle (resp. path) containing all the vertices of the graph. The energy of a graph is defined as the sum of the absolute values of the eigenvalues of the
